❓ Frequently Asked Questions

Q: What are the early signs and symptoms of Alzheimer’s disease?

A: Early signs can include memory loss, difficulty with familiar tasks, problems with language, and changes in mood or behavior.

Q: What are the main causes of Alzheimer’s disease?

A: The exact cause is not fully understood, but factors like genetics, age, lifestyle, and environmental influences are believed to play a role.

Q: How is Alzheimer’s disease diagnosed?

A: Diagnosis typically involves a medical history review, cognitive and neurological exams, and brain imaging techniques like MRI or PET scans.

Q: Is there a cure for Alzheimer’s disease?

A: Currently, there is no cure for Alzheimer’s disease, but treatments are available to help manage symptoms and potentially slow progression in some individuals.

Q: What are amyloid plaques and neurofibrillary tangles in Alzheimer’s?

A: Amyloid plaques are protein deposits that accumulate in the brain, while neurofibrillary tangles are twisted fibers of the protein tau, both disrupting brain function.

Q: Can lifestyle changes reduce the risk of Alzheimer’s disease?

A: Yes, adopting a healthy lifestyle including regular exercise, a balanced diet, social engagement, and mental stimulation may help reduce the risk of developing Alzheimer’s.
